[a/s] Disjoined walls

[Bearcatcher0702@xxxxxxx]

Help, please.
 I've been securing some 'loose walls' to 
the chassis of my Airstream.  
(The guy who sold it to me didn't tell me it had been in a pretty bad 
incident/accident/whatever!)
 Looks like it 'twisted' badly!...three walls were clean out of the tracks 
that joined them to the chassis walls.)  So those have been secured with new 
rivets and 
some aluminum strips secured one of the walls right to the floor.  (I was 
able to SLAM the main wardrobe closet back from the hall over 1-1/2 inches at 
that spot!)  

Two spots of the shower walls were ripped from the ceiling too!  So that's 
next? Any 
suggestions on how to repair the ripped 'chassis' up there (between the 
ceiling and the top of the walls)...short of removing the walls! (Please 
don't say I need to do 
that!  I've been thinking of using a very strong glue to repair the 
rips, and when it's dry, drill new holes for screwing the top of the 
walls to the chassis again.  Then before I screw them together, adding a 
layer of bonding (flexible...that stuff I get from West Marine)...glue 
between them before using the screws (molly) to 
pull them together. 
 Does this sound plausible?  I'm 'winging' 
it...so any technical advise will be appreciated.  I need to make the 
shower water-tight before moving in it...and the new date is end of 
August.  
So, HELP please.......all good advise will be considered!  ...........Cat
